DuckStation Git (2026/05/02) is a PlayStation emulator focusing on accuracy, speed, and compatibility with low-end devices. It includes a CPU recompiler, hardware (D3D11, D3D12, OpenGL, Vulkan) and software rendering, upscaling, and true color support. Key features comprise PGXP for geometric precision, adaptive downsampling, save state support, and various file format compatibility (e.g., bin/cue, PBP). The emulator allows for direct booting of homebrew executables, supports multiple controllers (including lightgun), and includes automatic updates and content scanning. Recent changes involve improvements in dynamic quantization and JIT write protection.

DuckStation Git (2026/05/02) has been compiled. DuckStation serves as an emulator for the Sony PlayStation(TM) console, prioritizing playability, performance, and maintainability. The objective is to achieve high accuracy while ensuring compatibility with low-end devices. “Hack” options are not recommended; the default settings should work with all playable titles, though some enhancements may lead to compatibility challenges.
